A conductor connects plates 2 and 5 while another conductor joins 1 and 3. The junction of 1 and 3 and the plate 4 are connected to a source of constant emf V0. Find (a) the effective capacity of the system between the terminals of source. (b) the charges on the plates 3 and 5. Given, d= distance between any two successive plates and A= area of either face of each plate.
